AUTOMATIC WAGON-BRAKE.

SPECIFICATION forming part Of Letters Patent NO. 363,435, dated RIay 24,1887.

Application filed J anuary 13, 1887 Serial No. 224,247. (No model.)

To aZZ whom it may concern: I Beit known that I, OnARLEs E. TEED, acitizen of the United States residing at Grifiins Corners, in the countyof Delaware and State of New York, have invented certain new and usefulImprovements in Automatic Wagon Brakes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to that class of wagonbrakes in which thebrake-shoes are automate.

ically applied to and released from the wheels by the holding back andpulling of the team,

I such action of the team serving to operate the brakes through themedium of a longitudinallymovable draft-tongue.

The objects of the invention are to simplify and strengthen theconnections between the draft-tongue and the brake-bar, and to soarrange such connections as to permit a free pivotal movement of thetongue; and furthermore, to insure the quick application and release ofthe brake-shoes, and also a powerful grip or holding action of theyshoes upon the wheels.

To the above purposes the invention consists, first, in the combination,with a tonguecarrying frame pivoted between the wagon hounds and adraft-tongue arranged to slide longitudinally upon the pivot-bolt of theframe, of a pair of levers pivoted upon the hounds directly above thepivot-bolt and connected with the tongue and with a brake-bar, so as tooperate the latter by the movements of the tongue, as hereinafterdescribed and claimed.

The invention further consists in the combination, with the brake-beam,of a pair of triangular or wedge-shaped brake-shoes arranged to slidevertically at the ends of the beam or bar and normally sustained intheir lowermost position by spring action, as hereinafter described andclaimed.

The invention consists, finally, in certain peculiar and novel featuresof general construction and arrangement, as hereinafter described, andspecifically pointed out in the claims.

In order that the invention may be fully understood I will proceed todescribe it with reference to the accompanying drawings, in which Figure1 is a plan view of the front axle of a lumber-wagon with myimprovements applied. Fig. 2 is an inverted plan view of the same. Fig.3 is a central longitudinal section of the same on the lines 3 3 ofFigs. 1 and 2. Fig. 4 is a detached view of one end of the brake-bar andone of the brake-shoes.

In the said drawings, A designates the front axle of a lumber-wagon, orof any other similar vehicle; and B B designate the wheels thereof.-Upon the upper side of the axle A are secured two bars, 0 C, whichconverge toward their front ends, and the rear ends of which are shownas connected by a curved bar, C. The bars 0 O are the hounds of thewagon, and are connected together about midway of their length, directlyabove their axle, by a cross-bar, C, as shown.

Between the ends 0 c of the hounds G, extending in front of the axle, isplaced the tonguecarrying frame, which consists of two peculiarly curvedbars, D D, connected together at their rear ends by metal bars-d d aboveand below the bars D, and at their front ends bysimilar metal plates orbars, d d and (1 d*. In order to strengthen this frame andtoincreaseits'durability the edges or sides of the bars D are bound withmetal strips (1 as shown. As previously stated this frame is placedbetween the front ends of the hounds, and said frame is held in positionby a bolt, E, which passes laterally through the front ends of thehounds and also through the bars D.

F designates the draft-tongue,which extends between the frontextremities of the barsD, at which point it is confined by the bars d dand thence between the plates or bars d,where it is confined betweenblocks (2* d, which are in turn held between said plates 01. The partsof the tongue,whioh lie thus within the tonguecarrying frame, areprotected by metal plates 0 e 6 and the plates 6 and the correspondingportion of the tongue are formed with elongated slots 6 through whichthe pivot-bolt E passes, so as to permit an endwise movement of thetongue. The plate 0, which covers the upper side of the tongue F,carries a U shaped loop, e, beneath which lie the inner ends of twolevers, G G, a pin, 6 extending downward through said loop and into thetongue, and also passing through elongated slots or eyes 9 in the leversG. The said levers G are piv: oted by pins it within loops H, similar tothe loop a, which are secured upon the upper sides of the ends 0 of thehounds and directly over the pivot-bolt E, as shown. It will be observedthat the relative position of thepivotal points of the tongue-carryingframe and of the lovers G, as well as the pin 6 are such as to preventany impediment to the pivotal movement of the tongue by the leversrelative to the hounds, so that the levers can be freely operated underall circumstances by thetongue. The outer ends of the levers G areextended beyond the outer sides of the hounds, and to these ends areconnected the front ends of rods I I, which extend rearwardly betweenthe axle and the crossbar O to the brake-bar J. The rear ends of therodsI are screw-threaded, and pass through the ends of the brake-bar, thesaid end of the bars being held adjustabiy between two binding-nuts, 11,on ach rod for the purpose of varying the throw of the bar and tocompensate for wear of the shoes.

The brake-shoes K consist each of a triangular or wedge shaped block,it, the three sides of which are inclosed by a metal plate, 7a. Thefront part of each plate It constitutes the face of the shoe, while therear part is sprung away from the block, as shown at as, so as to entera recess, j, in the front side of the brake-bar near its end. A metalplate, j, is secured to the front side of the brake-bar J at each endthereof, so as to overlie the recess j, and each of these plates extendsbetween the rear sides of the corresponding block, k, and the portion 00of the plate so as to support the brakeshoe upon the beam. These shoesare placed upon the brake-bar with their bases downward, as shown, andthe base of each shoe is formed with a notch or recess, 70, within whichenters the end of a spring-rod, L, which is secured to the under side ofthe brake-beam J by staples Z, the tendency of the spring-rod being tohold the brake-shoes in their lowermost position. By virtue of thisarrangement of the brake-shoes, whenever the team holds back so as toforce the tongue backward, the consequent forward movement of thebrakebar will bring the brakeshoes against the wheels, and the latterwill, by their revolution, move the shoes upward, and cause them to befirmly wedged between the tires of the Wheels and the brake-bars, thusgiving afirm grip to the shoes.

A pair of metal. strips, m extend along the upper sides of the bars 0,and a similar pair of strips, m, extend along the under sides of saidbars, said strips overlying the cross-bars C O, and underlying the axleA, so as to securely unite the parts. At their rear ends the strips mare bent to form loops m, in which the brake-beams J are supported andwork.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is-

1. The combination, with the pivoted tongue frame, the sliding tongueconfined therein, and the brakelevers pivoted upon the frame andconnected pivotally to the said tongue, of the brake-bar J, havingtherecesses j and their covering-plates j, and carrying the spring-rod L ofthe triangular brake-shoes K, having the plates is sprung away, as at x,and the recesses 70 at their lower ends to receive the ends of the rodL, substantially as specified.

2. The combination, with the wagon-hounds O and the tongue-carryingframe composed of the bars D and cross-bars d d d, of the pivot bolt E,extending through said frame andhounds, the longitudinally moving tonguehaving the loop 6* and pin 6 the levers G, having elongated slots 9 gand pivoted in loops Hand in thesaid loop 6*, the rods I, and the barJ,connected to said rods by the nuts i, substantially as set forth,

In testimony whereof I affix my signature in presence of two witnesses.
